KALGRE-N, OF MINNEAFOLIS, MINNESOTA, ASSIGNOR T0 THE J. R..CLARK C0., OF MINNEAPOLIS, MINNESOTA,o A CORPORATION OF MINNESOTA MACHINE FOR MAKING- VPAPER, COVERED IRONIN G BOARDS Application led August 10, 1928. Serial No. 298,770.

Y My present invention has for its object to provide a highly efficient machine for general use in applying and adhesively securing facings of normally iiexible material, such as paper, to a body member, and it is especially well adapted for use in applying such facings to both surfaces of the board or to of an ironing table, as disclosed and roadly claimed in my copending application filed June 4, 1928, under Serial Number 282,542 and entitled Ironing board.

As fully described in the above application, these paper facings should be strong, tough Yand glazed or otherwise treated so that they are substantially waterproof or impervious to water. The facing sheets are secured by glue or other adhesive material and applied under high pressure so that the glue will be forced into the pores and imperfections in the wood surface and said facing sheets caused to become practically integral parts of the board. Facing sheets applied to the opposite faces of the board as described, make it possible to use lower grades of lumber than would otherwise be usable, and also make it feasible to use a plurality of longitudinally extended strips to make up the board. These facing sheets reinforce the board against warpage and, moreover, protect the samev from moisture and heat applied thereto during the ironing operation that would tend to warp said board. Furthermore, the facing sheets give a smooth finished surface to wooden boards that have not been finished or smoothed with great care. The paper facing sheets may be made in color or in designs to give the board an ornamental and attractive appearance without the use of paint or varnish.

To the above end, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

The improved machine may be used to apply paper surfacing sheets to either or both sides of an ironing board and, as illustrated, said machine is equipped and operated to apply facing sheets A to both sides of ironing boards B. At the time the ironing boards B are fed to the machine to receive the facin sheets A, they are of the required width and length but not shaped to form the finished product. The ironing boards B are fed through the machine in endwise abutting engagement on a smooth fiat top or deck 12 and Cil a per an between unwound ortions of upper and low'-- intermediate tie bars'17, 18 and 19 respectively. The two pairs of posts 16 are transversely aligned. and the two posts thereof nearest the receivin end of the machine having their upper env s rigidly secured to the frame 15 by oblique braces 20.

Each roll of paper C is carried by a transverse horizontal shaft 21 havin a pair of vtruncated centering cones 22 w ich extend into the axial passage in said roll and directly support the same on the shaft 21 for rotation therewith. Said centering cones 22 are mounted for axial adjustment on the shaft 21 and held by said screws v23 where set. The shaft 21 for the upper roll C is removably j ournaled in open seats in bearing blocks 24, slidably mounted between the posts ofeach pair and are supported on upright adjusting screws 25 for vertical adjustment. These adjusting screws 25 have screw-threaded engagement with the upper cross-tie bars 17 and the bearing blocks 24 rest on the upper ends thereof. By manipulating either one of the screws 25,- or both thereof, the bearing blocks 24 may be raised or lowered to angularly adjust the shaft 21, hence the upper roll C in a vertical plane.

' The shaft 21 for'the lower roll C is removably journaled in openseats 27 in the lower ends of hangerstraps 28 secured by bolts 29 to the delivery end of the frame 15, with. freedom for a limited angular swinging movement longitudinally of said frame. Adjusting screws 30 having screw-threaded engagement with the frame 15 impinge against the hanger-bars 28 near their lower ends and hold the same where set. By manipulating either one or both of the screws 30, the hangerbars 28 may be angularly adjusted in vertical planes to angularly adjust the shaft 21 and hence the lower roll C in a horizontal plane.

The upper and lower combined feed andv pressure rolls 31 and 32 extend transversely of the machine, the former above the deck `12 and the latter below the same with its upper surface working in a transverse passage in said deck and substantially flush with the upper surface thereof. The shafts 33 for the rollers 31 and 32 are journaled in the bearing blocks 34 slidably mounted on and between the posts 16 of each pair and are supported for horizontal adjustment on horizontal eccentrics 35 which extend longitudinally of the machine. These eccentrics 35 are formed on bolts 36 intermediate of their ends and which bolts are turnably-mounted in the lposts 16 of each pair with said eccentrics extended therebetween. Nuts 37 on the bolts 36 normally hold said bolts from turning and hence the eccentrics 35. The ends of the bolts 36 are square in cross-section to receive a wrench by which said bolts maybe turned to rotate the eccentrics 35. Obviously by turning the eccentrics 35, the bearing blocks -34 may be raised or lowered to the position the opposing faces of the-pressure rolls 31 and 32, different distances apart and in parallel arrangement, orthe roll 32 may be adjusted to position its upper face in different adjustments in respect to the top ofthe deck 12.

The lower bearing blocks 34 rest directl on'the lower eccentrics 35 and the roll 32 a fords a base of resistance for the ironing boards B while passing between rolls 31 and 32. When there is no board B between the rolls 31 and'32, the upper bearin Ablocks 34 rest on the upper eccentrics 35 an which eccentrics at all times prevent the upper roll 31 from coming in contact with the lower roll 32 for a purposethat will presently appear. Inthis Vposition of the upper roll 31, the distance between the rolls 31 and 32 is less than the thickness of the boards B, so that duringt-heir movement between said rolls, the upper roll 31 is held lifted against the tension of a pair of h eavy coiled springs 38. The springs 38 are pressed between the upper bearing blocks 34 which afford seats therefore, and spring caps 39, which engage adj usting screws 40 as bases of resistance. These screws 40 have screw-threaded engagement With the intermediate cross-tie bars 19. Obviously by adjusting the screws 40, the tension of the springs 38 may be varied at will. The cooperating pressure rolls 31 and. 32 are driven in the direction of the arrows indicated in Fig. 3, to feed the ironing boards B through the machine, and at the same time press the unwound portions of the paper from the rolls C onto both faces of said boards. The lower roll 32 is driven direct from an electric motor 41, bolted to the ioor under the receiving end of the machine by the following connections, to wit:

Apbelt`42 runs over a relatively small pulley 43 on the shaft of the motor 41, and a relatively large pulley 44 on a short shaft 45 journaled in bearing brackets 46 bolted to the floor l forward of the motor 41. A second belt 47 runs over a relatively small pulley 48 on the shaft 45 and a relatively large pulley 49 on a transverse counter-shaft 50 journaled on the frame 15 under the deck 12 rearward of shaft of the lower roll 32. Intermeshing pinions 55 on the shafts 33 are provided for driving the upper roll 31 from the lower roll 32 The unwound portions of the rolls C extend between the pressure rolls 31 and 32 from the receiving end of the machine with the boards B therebetween. These unwound portions of the rolls C between said rolls and the. pressure rolls 31 and 32 have a thin coat of glue applied to their opposing faces by upper and lower glue fountains. Each glue fountain includes a relatively shallow reservoir 56 which extends transversely of the machine and contains a body of glue X. This glue X, during the operation of the machine, is kept at the proper temperature by a heating medium such as steam or hot water Y, circulated in a shallow chamber 57 on the bottom of each of said reservoirs. The upper reservoir 56 is supported rearward of the roll 431 by the oblique braces 20 and legs 58 attached to the frame 15 and the lower reservoir 56 is supported below the roll 32 on the posts 16.

Each glue fountain further includes a relatively large pick-up roll 59, distributing roll and a spreading roll 61. The pick-up rolls 59 extend into the reservoirs 56 with their under surfaces submerged in the gluev X and the distributing rolls 60 are provided with axial spaced circumferentially extended corrugations 62, see Fig. 8. Said distributing rolls 60 have peripheral contact with the pickup rolls 59 at the tops thereof. The spreading rolls 61 are circumferentially spaced from the distributing rolls 60 and supported just out of peripheral contact with the rolls 59.

The shaft for the upper pick-up roll 59 is journaled in bearing blocks 63 mounted on the oblique braces 20 with freedom for a limited longitudinal movement and are held in different adjustments between pairs of opposing adjusting screws 64 on said braces. The shafts for the upper distributing and spreading rolls 60 and 61 respectively, are j ournaled in open seats in bearing plates 65 on the oblique braces 20. Obviously by adjusting the screws 64. the upper pick-up roll 59 may be raised or lowered to vary its peripheral contact with the distributing roll 60. The shaft of the lower pick-up roll 59 is journaled in bearing blocks 66 slidably mounted on and between the posts 16 of each pair and are supported on adjusting screws 67 having screw-threaded engagement with the lower cross-tie bars 18. Obviously by manipulating the screws 67, the lower pick-up roll 59 may be raised or lowered to vary its peripheral contact with the cooperating distributing roll 60.

The unwound portion of the upper roll C is held by the roll 31 and guide roll 68 bent over the upper distributing roll 60 and upper spreading roll 61 for peripheral contact therewith, as best shown in Fig. 3. Said guide roll 68 is journaled in bearings 69 mounted for a limited movement on upright osts 70 on the ends of the upper reservoir 56. I1)"he bearings 69 are held in different adjust` ments by pairs of opposing set screws 71 on the posts 70. From the upper spreading roll 61 the unwound portions of the upper roll C passes under the pressure roll 31 for application to the upper faces of the ironing boards B.

The unwound portion of the lower roll C is held by a pair of guide rolls 71 bent over the lower distributing roll 60 and lower spreading roll .61' for peripheral contact therewith as best shown in Fig. 3. The shafts of 4the guide rolls 71 are journaled in bearing blocks 72 mounted on short posts 73 on the ends of the lower reservoir 56. Said bearing blocks 72 are adjustably heldwhere set by pairs of opposing set screws 74 having screwthreaded engagement with brackets on the posts 73. From the last guide roll 71, the unwound portion of the lower roll C passed through the passage in the deck 12 and over the roll 32 for application to the under faces of the ironing board B. By adjusting each pick-up roll 59 in respect to the cooperating distributing roll 60 said distributing roll receives from said pick-up roll the desired amount of glue. The glue on the corrugated distributing rolls 60 is deposited in rows on the contacting surfaces of the unwound portions of the rolls C and these rows of glue are evenly s read over the unwound portions of the roll C) by the spreading rolls 61. The unwound portions of the roll C to which glue has been applied in passing between the rolls 31 and 32 are pressed onto both faces of the board B between the rolls 31 and 32. The tension of the springs 38 on the roll 31 is such that the glue is pressed into all of the pores and imperfections in the wood surfaces and the facing sheets C becomes substantially integral part of the ironing boards B.

The unwound portions of the rolls C attached by glue to the ironing board B are unwound thereby from the rolls C through the glue fountains and between the rolls 31 and 32 where they are pressed onto both faces of said boards.

To place tension on the unwound portions of the rolls C, and prevent said rolls from unwinding except under the feeding movement of the ironing boards B by the rolls 31 and 32, said rolls C are subjected to friction devices. These friction devices as shown, are in the form of flexible metal bands 75 laid transversely over the rolls C in peripheral contact therewith. The band 75 for the upper roll C lis anchored at 76 to the oblique braces 2O and the band 75 for the lower roll C is anchored at 77 to the frame 15. The rolls C are unwound in reverse directions from the pull on-the'friction bands 75 by the weight 78 and tend to lift said weights and produce sufficient friction on the Vrolls C to prevent thesame from unwinding except under the'feeding action of the ironing boards B.

From the pressure rolls 31 and 32 the n boards A pass between a pair of cooperating idle squeezing rolls 7 9 having pliable facings of rubber or other suitable materials. The shaft of the lower'squeezing roll 79 is journalel in bearing brackets 80 on the'sides of the frame 15 andthe shaft of the uppr roll 7 9- is journaled in bearing blocks 81 unted in the brackets 80 for limited raising and low-0. ering movements. Set screws 82 having vsqueezing rolls 7 9 press the glue still further into the pores and imperfections in the boards B and complete the application of the surfacing sheets Ao thereto. The surfacing sheets A are cut from the unwound portions of the rolls C after the ironing boards B have passed from between the squeezing rolls 7 9. The feeding movement of the-ironing boards B between the squeezing rolls 79 is produced by their endwise engagement with the following ironing board B to which movement is imparted by the driven pressure rolls L31 andl 32 An upper knife 83 and a cooperating lower knife 84 have opposing beveled cutting edges and are provided for cutting the surfacing sheets A from the unwound portions of the rolls C after the ironing boards B have passed from between the squeezing rolls 79. The lower knife 84 at its ends is loosely seated in open pockets 85 formed in fixed members 86 on the frame 15 and held thereby against movements in all directions except movements toward or from the upper knife 83.

' Set screws 87 having screw-threaded enga-gement with the bars 86, extend into the pockets 85 and support the lower knife 84 for vertical adjustment with its cutting edge extending through a .passage in the deck 12 and slightly above the upper surface thereof for severing the lower facing sheet A from the unwound portion of the lower roll4 C. As the lower knife 84 is worn away by usage and grinding, the same may be kept in proper adjustment by the set screws 87 v The upper knife 83 is carried by a' pair of heads 88 to which said knives at its ends are rigidly secured. These heads 88 are slidably mounted in ways 89 on the sides of the frame 15. The upper knife 83 is lowered to cut the upper surfacingsheet A from the unwound portion of the upper roll C and then raised to an inoperative position by a pair of eccentrics 90 on the ends ofa transverse shaft 91 'ournaled in bearings92 on the frame 15.- ese eccentrics 90 have eccentric straps 93 to which one of the ends of a pair of connecting rods 94 are attached. On the other' ends ofthe connecting rods 94` are bearings 95 in which trunnions'96 on the heads 88 are mounted. v

These bearings v9 5 are attached to the connecting rods 94 b 'screw-threads, whereby vthe upper sur acing sheet A forces the lower facing sheet A downward onto the lower knife 84 and produces a cutting action that severs said lower surfacing sheet, at the same time, the upper facing sheet is severed by the knife 83. The distance the cutting edge of the lower knife 84 projects above the upper surfaceof the deck 12 is so-'slight vthat itv does notzinterferewith the feeding movement of the ironing boards B through the machine.

The shaft 91 is ldriven from an electric motor 97 by a belt 98 which runs over.` a small pulley-99 on the shaft of said motor and a large pulley 100 loose on the shaft 91. Said motor 97 is'bolted to the floor under the machine. A yieldingly set clutch 101 having a radially projecting pin 102 is provided for connecting thepulley This clutch 101 is normally held released s0 that the shaft 91 is idle b a horizontally extended vlever 103 .pivote at 104 to the frame 15 and having near its pivoted end a laterally projecting stop shoulder 105 with which the clutchpin 102 engages to hold the clutch 101 released. The lever 103 isnormally held by gravity with its shoulder 105 in the path of movement of the clutch pin 102. y

To operate the knife 83 the operator lifts the lever 103 to move its stop shoulder out of the path of movement of the clutch-pin 102 to release the clutch 101 and allow the same to automatically set and connect the pulley 100 to the shaft 91. After the clutch pin 102 has been vmoved beyond the stop shoulder 105 the operator releases the lever 103 and permits the same to return by gravity to a normal position with its stop shoulder in the pathof movement of the clutch pin 102 to be reengaged thereby when the shaft 91 has made one complete rotation. During this complete-rotation of the shaft 91 the upper knife 83 has been moved by the connections therefore from the shaft 91 to a cutting position and then returned to its raised or normal position.` y

ing rolls 79 and position the same with the vjoint between the abutting ends of two of the boards B aligned with the knives 83 and 84 and for automatically releasing the clutch 51 to stop the rotation of the pressure rolls 31 and 32 that produce the feeding action of the boards B,the following connections are provided, to Wit:

A trip bar 106 having an adjustable abutment 10T is pivoted to a pair of upstanding short crank arms 108 on a pair of transverse rock shafts 109 journaled in bearings in thc sides of the frame 15. Said trip bar 106 extends longitudinally of the machine at the transverse center thereof and under the deck 12 with the abutment 107 projecting upward through a notch 110 in the delivery end of the deck 12 to be engaged by the forward end of one of the ironing boards B when its rear end is aligned with the knives 83 and 84 between which it has just passed.

The abutment 107 at its lower end is bifurcated and slidably mounted on the trip bar 106 for adjustment longitudinally thereof. A set screw 111 having screw-threaded engagement with the prongs of the bifurcated end of the abutment 107 impinges against the trip `bar 106 and rigidly holds said abutment where set. By adjustably mounting the abutment 107 on the trip bar 106 the same may be set for ironmg boards that vary in length.

The rear rock shaft 109 is connected to the clutch lever 52 by a bell-crank 112 pivoted to the frame 15 and having one of its arms connected by a rod 113 to a short crank arm 109 on said rockshaft and its other arm is connected by rod 114, to the lever 52, see Fi 9.

t the time the abutment 107 is engaged by one of the ironing boards B, a slight endwise movement is imparted to the trip rod 106 which operates the connections to the clutch lever 52 and thereby releases the clutch 49 and stops the rotation of the rolls 31 and 32 v from the motor 41 and at the same time, aligns the rear end of the board with the knives 83 and 84. The operator then lifts the lever 103 to release the held clutch 101 and allow the same to set and thereby complete the connections from the motor 97 to the upper knife 83 for reciprocating said knife as previously described and cause the knives 83 and 84 to sever the two surfacing sheets A from the unwound portions of the rolls C. The operator then lifts the ironing board B from the deck 12.

The free end of the trip bar 106 is shaped to form a handle 115 by which the operator may impart return movement to said bar and again set the clutch 49 to drive the rolls 31 and 32 and position the abutment 107 for the neXtc-llowing ironing board B to which the surfacing sheets A are being applied. The clutch lever 52 may be manually operated'at their entire width as will, to set or release the clutch 49. In 'case the ironin' boards B vary slightly in length, the surfacing sheets A will sometimes be cut at one side of the joint between the abutting ends of two boards, but this is immaterial as the boards may be 'easily separated at the time they are removed from the machine. A guide bar 116 on the deck l2 is provided for directing the ironing boards B between the rolls 31 and 32 and at right angles to the axes thereof. This guide bar 116 is rigidly secured to the deck 12 but with freedom for adjustment transversely thereof by a pair of anchor members 117. These anchor members 117, as shown, are permanently secured to the guide bar 116 extend outward therefrom and have slots 118 which extend transversely to said bar. Screws 119 having screw-threaded engagement with the deck 12 extend through the slots 118 and clamp to the anchor members 117 on the deck 12. The slots 118 and the anchor members 117 permit the guide bar 116 to be edgewise adjusted transversely of the deck 12 to transversely align the boards B with the unwound portions of the roll C so that the surfacing sheets A will be properly applied to said boards during their traveling movement between 'the rolls 31 and 32 with said boards.

By adjusting the bearings 24 and the hanger-bars 28, the upper and lower rolls C may be angularly adjusted to hold the unwound portions of said rolls stretched taut throughout they pass under the guide rolls to the glue fountains and from said fountains to the rolls 31 and 32. As previously stated, the feeding movement of the boards B on the deck 12 by the rolls 31 and 32, imparts a like movement to the unwound portions of the roll C by their adhesive attachment to said boards.

After the ironing boards B have been removed from the machine, they are trimmed to shape and their edges finished.
